If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

package.json declares a postinstall lifecycle hook that runs `calc.exe` on the installer's machine during `npm install`. The main entry point exports only an empty `requestHooks` array, providing no actual Insomnia plugin functionality — the package's sole effect is the arbitrary command execution at install time. The name self-identifies as a proof-of-concept and mimics the Insomnia plugin naming convention with a leet-substituted variant, indicating the package exists solely to demonstrate/exploit install-time RCE. While calc.exe itself is benign, the postinstall hook establishes full arbitrary-command-execution capability against any developer installing the package on Windows.
